Santorum's tit for tat on Roe v. Wade anniversary

The Supreme Court's decision on Roe v. Wade turned 40 years old Monday. Rick Santorum, who has made family and tradition a cornerstone of his campaign, used the occasion to contrast his voting record on abortion against President Barack Obama and each of the Republican candidates still standing.

"[Obama's] record of support for abortion is radical and extreme," Santorum wrote in an op-ed for the Wall Street Journal. "He supported federal funds for abortion through ObamaCare and told Catholic Charities that there was no room in the inn if they wanted to help women abused by sex traffickers and be pro-life at the same time."

Of Ron Paul's libertarian streak,  he said, "what is liberty without the right to life?"

Santorum accused Newt Gingrich of having "pushed social issues to the back bench."

But the sharpest barbs were saved for Mitt Romney. "Romney's passion for life was apparently overwhelmed by Democrats when he put Planned Parenthood on the advisory board for RomneyCare and did not fight government-funded abortions while governor of Massachusetts," Santorum wrote. "He was, it seems, too intimidated to support judges who understood the plain meaning of the Constitution on the right to life."
